Benefits of technology

The present invention provides a system and method for adapting an application source rate to a load condition. This allows for fine tuning of CODEC rate selection in response to available resources at connection setup, improving user experience. Additionally, it allows for a more rapid connection setup if a requested CODEC rate is not available, and fine tuning of CODEC rate during connection operation. Overall, this invention allows for better performance and efficiency in connection setup and operation.

Problems solved by technology

The eNB may become overloaded when traffic load increases, such as during busy hours of operation.
The eNB may become overloaded with respect to its radio links, transport network, and / or due to hardware and / or software limitations in network equipment.

Embodiment Construction

[0035]The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0036]The present invention will be described with respect to preferred embodiments in a specific context, namely a 3GPP LTE compliant communications system. The invention may also be applied, however, to other communications systems, such as those that are 3GPP LTE-Advance, WiMAX, and so forth, compliant.

[0037]FIG. 1 illustrates network components in a communications system 100. Network components that may be involved in a connection between a UE 105 and a far end device 110 are shown. The connection may have originated at UE 105 and terminated at far end device 110 or origi...

Abstract

A system and method for adapting an application source rate to a load condition are provided. A method for forming a connection includes receiving a service authorization request for service between the first device and the second device, requesting a formation of a first bearer at a first data rate between the first device and the second device, and determining if the first bearer was formed. The method also includes transmitting a first positive response if the first bearer was formed, forming a second bearer at a second data rate if the first bearer was not formed, and completing the connection. The service authorization request includes a request to establish a connection at the first data rate, and the second data rate is different from the first data rate.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 187,654, filed on Jun. 16, 2009, entitled “Method and Apparatus for Adapting an Application Source Rate to a Load Condition in a Wireless Communications Network,” which application is hereby incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates generally to a system and method for wireless communications, and more particularly to a system and method for adapting an application source rate to a load condition.BACKGROUND[0003]Generally, in 4 G communications systems, such as Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) compliant communications systems, voice communications may be supported in the form of voice over Internet protocol (VoIP), wherein voice data is transmitted as a data packet. For example, a user equipment (UE), which may also be commonly referred to as a mobile station (MS), may use an adaptive multi-rate (AMR) speech coder and decoder...
